anyway, why not generate the CS on our own? We can CS when we get a
CS from the PLA, or if it is a write and it goes to a specific area
which we can decode on our own. IMHO, it does not matter if "normal"
RAM is written, too, since an update of the battery-backed RAM should
not be that often, should it? Anyway, any area you find to be decodable
ease can be choosen.
Just more thoughts,
Spiro.
